there is noting happen,it shuld be print 中文.
This caused me to delete a large number of files by mistake when I used grep -v whitelist to delete files.

What is the expected behavior?

Under normal Ubuntu, grep can be matched to Chinese.

Thanks. As mentioned in the issue grep works fine if compiled on device, so there has to be some configure option causing it

ok,I tried to compile the latest version in Termux，but failed.
I have used the version 3.1 in Ubuntu, and after recompilation, it can work normally.
